2. Drip irrigation and sprinkler irrigation technology have been popularized in China, but after all, compared with the current water resources situation and traditional irrigation facilities, drip irrigation and sprinkler irrigation equipment need capital investment, and they are not once and for all, and their equipment loss is also quite large, so it is still a bit difficult to popularize at present with limited knowledge and understanding, but in high-yield industries such as greenhouse and greenhouse,
3. Israel-Water-saving irrigation promotes agricultural and economic development.
Israel's agricultural irrigation technology has experienced several revolutions, such as flood irrigation, furrow irrigation, sprinkler irrigation and drip irrigation, and each revolution is a great leap in agricultural water-saving technology. In the early 1950s, when Israel was founded, sprinkler irrigation technology replaced long-term flood irrigation. By 1965, drip irrigation technology was first proposed. Compared with other irrigation methods, the main advantages of drip irrigation technology are: it can realize uniform irrigation on sloping land; The synchronous integration of fertilization and irrigation can be realized, that is, the liquid fertilizer is mixed with water for irrigation before the end of the irrigation system; Can greatly reduce the growth of weeds; Accurate irrigation can be realized, water and fertilizer are concentrated in the roots of plants, the efficiency is extremely high, and the invalid volatilization and leakage of water are reduced. ...
4. The invention and development of drip irrigation technology is a milestone in the development history of agricultural production technology in Israel in recent decades, and it is Israel's greatest contribution to the world agricultural water-saving irrigation technology and methods. At present, 80% of irrigated land in Israel is irrigated by water and fertilizer during drip irrigation (that is, "fertilizer irrigation", irrigation and fertilization are carried out at the same time and completed at one time). The water consumption per unit area of land is reduced by 50% ~ 70%, and the agricultural water consumption is greatly reduced. At the same time, based on its good experience in agricultural irrigation, Israel has developed a series of new irrigation technologies, which have successfully entered the international market.
It is with this set of water-saving system and measures that Israel has developed agriculture in the valley area and built an oasis in the desert, making Israel's agriculture among the developed countries.
